Proto J5434MH 34mm 6-point 1/2 in Drive Hand Socket

Product Description

The PROTO J5434MH is a 34 mm, 6-point hand socket built for professional mechanical and industrial applications. Machined from alloy steel with a chrome-plated finish, this standard-length socket fits a 1/2 inch drive and delivers reliable torque transfer on hex fasteners. At 1-27/32 inches overall length, it is sized for general-purpose wrench work without the added bulk of deep sockets. The 6-point design reduces fastener rounding under high torque loads, making it a preferred choice for technicians working on heavy equipment, fleet vehicles, and industrial machinery. This socket meets ASME B107.5M standards and carries a limited lifetime warranty.

This socket is suited for automotive, fleet maintenance, industrial, and general mechanical service environments. It is a standard-duty hand socket intended for use with 1/2 inch drive ratchets, breaker bars, and torque wrenches. The 34 mm size is common on larger fasteners found in drivetrain components, suspension assemblies, and heavy equipment. Licensed mechanics, fleet technicians, and maintenance professionals in industrial facilities will find this socket a practical addition to a 1/2 inch drive set.

Installation Notes

Installation is performed by qualified mechanics or maintenance technicians using standard 1/2 inch drive hand tools. Ensure the socket is fully seated on the fastener before applying torque to prevent slipping or rounding. Inspect the socket and drive square for wear or cracks before each use. This socket is not tether capable and should not be used in overhead or elevated work zones where dropped-tool hazards exist.
